Hello,

I use the MESHFREE solver. I wanted to know if there was a way to plot volume flow rate or mass flow rate across a surface over time.

I am relatively new to Paraview. Any help would be appreciated.

What is the format of your data ?

Can you share a dataset ?

Its a case file. ENSIGHT binary format.

So there are two case files written, one for the boundaries (geometry) , and the other for the model (solution).

- Open your model
- Select the cells you want to inspect
- Filters -> Extract Selection
- Filters -> PlotDataOverTime

But I have not compute the mass flow.

Is it possible to compute the mass flow on Paraview and then plot it?

You can implement any kind of computation using a Programmable Filter.

Isnâ€™t there a filter already available to perform this computation?

- I could integrate the variables and use the Calculator filter. But the velocity is available only as vectors.
- Could you tell me how the surface flow filter works?

Even after computing the mass flow, can it be plotter over time?

You can use the calculator with vectors.

Could you tell me how the surface flow filter works?

The flow integration filter integrates the dot product of a point flow vector field and surface normal. It computes the net flow across the 2D surface. It operates on any type of dataset and produces an unstructured grid output of a single point containing the result.

Even after computing the mass flow, can it be plotter over time?

Yes, use PlotDataOverTime
